Students evaluated the product in the advertisement on a scale of 1 to 7, with 1 being the most unfavorable rating and 7 being the most fa vorable. The paper reported that a one-way ANOVA on the product evaluation index had F = 6.29 with P < 0.05.13 a. identify the populations and the response variable. b. what is the…Stephens, atkins, and Kingston, 2009 conducted an experiment in which participants were able to tolerate moore pain when they were shouting their favorite swear word than when they were shouting neutral words, Identify the dependent and independent variables for this study
